Specification of Letters Patent.

Patented May 18, 1909.

Application filed February 10, 1908. Serial No. 415,117.

T 0 all whom it may concern:

Be it known that I, RUBERT STEWART ROYCE, a citizen of the UnitedStates, residing in the borough of Brooklyn, county of Kings, city andState of New York, have invented certain new and useful Improvements inKnapsacks, of which the following is a specification, reference beinghad therein to the accompanying drawings, in which Figure 1 is aperspective view of the device showing the two members tightly strappedtogether; Fig. 2 a similar view of the device arranged to be carried onthe back; Fig. 3 a similar view showing the outer shell or member of theknapsack converted into a set of shelves; Fig. 4 a perspective viewshowing the bottom and sides of the inner member of the knapsackunfolded to form a table top; Fig. 5 a detail perspective view of oneend of the inner member of the knapsack, the end piece being detachedfrom the bottom and sides; and Fig. 6 a detail vertical sectional viewshowing the means for supporting the ends of the inner member of theknapsack within the outer member to form shelves.

One of the main objects of this invention is to provide a knapsackformed of two telescoping members which may be securely strappedtogether.

Another object of the invention is to so construct the parts or membersof the knapsack that one of them may be knocked down, or divided intoseveral sections, each section of which may be used for some usefulpurpose about a camp.

The purpose of this invention is to provide a convertible, light, strongand preferably water-proof knapsack to hold. a campers outfit duringtransportation, and to so construct it that each part will serve auseful purpose in the camp.

Referring to the various parts by numerals, 1 designates theouter partor cover of the knapsack and 2 the inner part or tray. The traytelescopes within the cover in the ordinary manner of the well knowntelescoping traveling case. I prefer to form these parts of light,stiff, water-proof material such as the so-called fiber board, but, ofcourse. it will be understood that they may be made of any suitablematerial. The cover or outer member is provided with suitable braces 3at its corners, and, of course, it may be braced and reinforced in anysuitable manner.

The inner member or tray of the knapsack is formed with the bottom 4 andwith the sides 5 which are flexibly connected to the bottom by anysuitable form of hinge. I have shown the sides connected to thelongitudinal edges of the bottom by means of flexible leather hingestraps 6 so that the sides and the bottom may be brought into the samehorizontal plane by folding down the sides. The ends 7 of the tray areadapted to be detachably connected to the bottom and sides and for thispurpose they are each provided with a horizontal flange 8 which isadapted to fit under the bottom 4 of the tray and with the verticalflanges 9 which are adapted to fit against the outer surfaces of theside pieces 5, when said sides are in their vertical positions andsubstantially perpendicular to the bottom part To hold the bottom flange8 of the end piece'in engagement with the bottom of the tray, snapfasteners 10 are provided, one member of said fastener being carried bythe flange and the other member thereof being secured to the bottom ofthe tray in such position that when the end is in position said. twoparts of the snap fastener register and may be easily connectedtogether. To secure the vertical flanges'9 to the sides 5 of the tray Iprovide two-part snap fasteners 11, one part of which is carried by theflanges 9, the other part being connected to the sides in such aposition that the two parts will register when the ends are in positionon the body of the tray. .Each of the end sections is also provided withan inner horizontal flange 12 which is adapted to fit over the bottom ofthe tray when the end section is in position, to make a tight jointtherewith, and to prevent accidental separation of the fasteners 10.Each of the end sections is also provided with inner vertical flanges 18which engage the inner surfaces of the sides 5 so that the sides fit inbetween the flanges 9 and 13. This makes a strong construction, not onlybracing the corners of the tray, but preventing the accidentalseparation of the fasteners which connect the end sections to the bodyof the tray. It

will, of course, be understood that'any. suitable form of fasteners maybe us'ed,.the two part snapfasteners shown being very convenient andefficient.

The longitudinal sides of the cover are provided on their inner surfaceswith transverse straps or cleats 14 of flat material, preferablycomparatively wide strips of the same material of which the cover ismade.

These cleats are secured to the side walls of the cover along one o'i'their edges, their tree edges being off-set slightly from the cover, asshown clearly in Fig. 6. When the end.

pieces or sections of the tray are detached from the bottom and sidesthereof the flanges 9 thereon may be engaged over the cleats 14, asshown clearly in Figs. 3 and 6 to 'l'orm compartments within the cover.l ly rtand 1O ing the cover on its end, or by suitab y susendinc' 1t sothat the ends '7 are substanier tially horizontal, a set of shelves isprov which is very desirable and very con-v in camp. As the entire devicis mace of water-proof material, it will be seen that a set of shelvesmade up in this way will form a very desirabl place for storing loodsupplies, ammunition, apparel, etc.

When the end. sections ar detached from the bottom and sides of "1e traythe sides may be folded down into the plane oi the bottom to form aconvenient table top, which may be supported on sticks, as shown clearlyin Fig. e.

To secure two parts of the knapsack together I provide a strap 15 whichpasses transversely around the case, as shown clearly in Figs. 1 and f3.Shoulder straps are formed from a strap 16. The two ends of this strapbuckl d to the lower end oi the cover near the side edges thereof, as

shown at 17 in Fig. 1. Before being secured both ends of this strap arepassed through a keeper or loop 18 secured to one of the end sections,said end section being arranged,

when the tray is placed within the cover, at

the opposite end of the cover from the buckles 17 so that the ends ofthe strap 16 separate or (iii ergo from said loop to the buckles 17. Thelooped end of the strap is passed through bails 19 and 20 secured to theend of the cover opposite the buckles 17 said bails being secured to thecenter of said end. I provide two bails l9 and 20 to per mit of theextension of the two parts 1 and 2 01" the casing without the necessityof providing an unduly long strap 16. l i hcn the case is extended thestrap will be looped through the bail 19, but when it is in its normalposition, the tray 2 being entirely inclosed by the cover, the strapwill be looped between. both bails 19 and 20 in order to take up aportion of the slack thereof.

The strap 16 may be arranged as shown in Fig. 3 to form a supporting forthe shelves. In this arrangement oi' the strap it is looped through thebail 20 as shown.

It will be noted that the shoulder straps are connected to the outercasing or cover of the knapsack and extend around the bottom I of theinner member so that when the knapsack is carried on the back the bottomof the inner member will be against the back of the person carrying theknapsack. As the will extend across the bottom of the inner.

member and assist in securely holding it in position within the cover.This is a very important feature of my invention and serves as a veryel' i'ective means of securing the two parts of the knapsack together,particularly when they have been packed with material and are stacked upeither for transportation or storage. In forming a knapsack of twotelescoping parts or members it is necessary to provide means foreffectively securing the two members together so that the device may besubjected to rough usage without any danger of the two parts or membersbecoming separated. By my arrangement of the shoulder straps l securethis without the necessity oi employing any extra straps, ex.-

cept the small strap 15 which is desirable for holding the two partstogether when the ck is being placed on the back or removed therefrom.it will, of course, be understood that the strap 15 will be unnecessaryfor holding the two parts together when the knapsack is in position onthe back of the person carrying it.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. n knapsack consisting of a cover and an inner removable tray'formedin sections detachably connected together, and means whereby sections ofthe tray when detached maybe secured to the cover to form compartmentstherein.

2. A knapsack consisting of two parts adapted to telescope one withinthe other, one of said parts being made up of sections detachablyconnected together, the other part being provided with means whereby thesaid detached sections may be inserted there.- in to form compartments.7

3. [i knapsack consisting of two telescoping sections constituting anouter cover and an inner tray, the tray being formed with detachableends, means secured within the cover part to support the detached trayends I to form compartments within the coverpart, whereby said coverpart with the saidends may be used as a casing containing shelves 4. Aknapsack consisting of two rectangular box-like telescoping parts, oneconstituting a cover and the other a tray adapted to be received withinthecover, said tray being formed with detachable ends, a bottom, andides flexibly connected to the longitudinal edges of the bottom topermit them to be folded into the plane of the bottom, means 65 shoulderstraps are connected to the outer l within the cover to support theendsof the tray when they are detached to form compartments in thecover, whereby the cover and the tray ends may be used to form a set ofshelves and the bottom and sides of the tray may be used as a table top.

5. A knapsack consisting of two telescoping parts, one constituting anouter cover and the other a tray to be received within the cover, saidtray being formed with detachable end sections, each detachable endsection being provided with a bottom flange to engage the outer surfaceof the bottom of the tray and with vertical flanges to engage the outersurfaces of the sides of the tray, and fastening means adapted 'toconnect said flanges to the adjoining portions of the tray, each of saiddetachable ends being provided with inner flanges adapted to overlap theadjoining portions of the bottom and the sides of the tray.

6. A knapsack consisting of two telescoping parts, a pair of bailssecured to one end of the outer part near the middle thereof and in linewith each other, a pair of buckles secured to the other end of the outerpart near the side edges thereof, a loop secured to the bottom of theinner part adjacent to the bails on the outer part and a strap passedthrough the bails and through the loop on the bottom of the inner part,the ends of said strap being connected to the buckles on the outer part,whereby said strap will extend across the bottom of the inner part andform the shoulder straps, said strap also serving to hold the outer partover the inner part when the device is in position on the back of thecarrier.

7. A knapsack consisting of two telescoping parts, one constituting acover and the other a tray to be received within the cover, detachableend sections for said tray, each end section being provided with abottom flange to engage the outer surface of the bottom of the tray andwith vertical flanges to engage the outer surfaces of the sides of thetray, fastening devices carried by said flanges and adapted to connectthem to the adjoining portions of the sides and bottom of the tray,each' end section being also formed with inner flanges to engage theinner surfaces of the sides and bottom of the tray.

8. A knapsack consisting of two telescoping parts and shoulder strapsconnected to the outer part, said straps being formed by securing thetwo ends of a single strap to one end of the outer part near the sideedges thereof and connecting said strap midway its ends to the other endof the outer part at the center thereof, whereby the two parts of thestrap will converge toward one end of the outer part and the twoportions of the strap will extend across the bottom of the inner part,whereby when the knapsack is carried the bottom of the inner part willbear against the back of the carrier and the shoulder straps will holdthe outer part over the inner art.

In testimony whereof I hereunto afliX my signature in the presence oftwo witnesses this eighth day of February 1908.
